To all whom it may concern.

.Be it known that I, KARL ARNSTEIN, a citizen of Czechoslovakia,residing at Friedrichshafen-on-the-Bodensee, Germany, have inventedcertain new and useful Improvements in Wire and Rope Clamping Devices,for which I have filed an application in Germany October 21, 1921, andof which the following is a specification.

My invention has reference to clamping means for wires, wire ropes andthe like, and it particularly provides for the passing of the wires orropes substantially or approximately or exactly through the median lineof the coupling. In accordance with my invention, the wire or rope to betightened or the wires or ropes to be intersectingly connected orcoupled with each other or with other parts are passed betweenoppositely concave and convex curved clamping surfaces so as to bedeflected.

This application is a division of my application for patent filedOctober 23, 1922, Serial No. 596,488.

The clamping surfaces may be formed of complete discs provided withsector-shaped projections and sockets, the outer surfaces of which arespherically curved in opposite sense, and engaged with each other. Theclamping members are connected to each other by several screws,eccentrically arranged, in such a manner that the wires are passedbetween the two screws at the desired angle, recessed portions beingprovided for the passage of the wires between the apexes of theprojecting sectors. 7 The clampin device according to my inventionofl'ers t e advantage that the wires are held fast along an extendedclamping surface and are maintained between only two clamping members,each of the wires being passed between the gaps presented by theprojection of one of the members and between the projections of theother member. This aifords the possibility of constructing a couplingdevice of very compact form requiring very little space. The clampingmeans, according to my invention, is adapted both for the clamping inposition of single or several wires or the like running in one directiononly, as well as for the reception of a plurality of crossing orintersecting wires It is particularly adapted for special purposes,forexamplein the building of hulls for air-ships of the'rigidtype,'wherein wires, wire ropes and the like aregto be secured to sheetmetal members, flange bars and the like.

In the drawings afixed to this specification and forming part thereof, adevice embodying. my invention is shown by way of example. In thedrawings- Fig. 1 is a side view, the clamping members being shownsomewhat separated from each other.

Fig. 2 is a cross section on the line IIII in Fig. 1, and

Fig. 3 is a perspectiveview, the clamping members being separated.

Referring to the drawings, each of the two clamping discs a and a isprovided with projecting sectors 1) and b, respectively, the outersurfaces of which are spherically curved and which are adapted to engagein corresponding recesses 0 and 0 respectively, of the other clampingmember, the bottoms of the gaps being spherically curved in conformitytherewith. The curvature of the segmental surfaces determines thebending of the wire to be gripped, as shown for instance in Fig. 1 ofthe drawing. The Wires to be clamped or coupled are arranged to extendeach across the gaps or recesses of one and the sectors of the otherclamping member, a gap y separating the convexshaped sectors of eachmember.

The clamping members are pressed against one another by a pair of screwbolts 6 with nuts 7, the bolts being fixed in one of the members withabout one half of the circumference of the foot portion of each bolt,extending through a semi-cylindrical groove 03 provided in a lateralface of a sector of this member, while similar grooves are provided inthe lateral faces of thesectors of the other member for the reception ofthe free ends of the screw bolts.

Fig. 1 shows the way in which the wires can be fixed by means ofthisdevice to a plate 9 or to a strut girder or the like.

The particular configuration, relative position and cooperation of theseveral parts of the novel device allows clamping or coupling a pair ofintercrossing wires, ropes or the like right in the diameters of thecoup- I ling discsfvvith the Wires-or the like inter- Wires, ropes andthe like, comprising in com- V bination, tWo substantially disc-shapedcoupling members, convex surfaces on each disc with two oppositelydisposed concave recesses, the CODVQX portions of each disc fitting inthe concave recesses of the other disc, a central gap between the convexportions of each. disc means for clamping said discs together. 1

2. Clamping and coupling device for Wires, ropes and the like comprisingin combination -tWo substantially disc-shaped couplin members, convexsurfaces on'each disc witi two oppositely disposed'concave recesses, theconvex portions of each disc fitting in the concave recesses of theother d sc, a central gap between the convex portions of each disc andscrew bolts extending through said discswith part of theircircumferences surrounded by grooves in diametricallyoppositelateralfaces of said convex portions.

In testimony whereof I aflix my-signature.
